The internal angles of any triangle total 180 degrees. In this right angles triangle, one angle has to be 90 degrees, leaving 90 degrees for the total of the unknown angles. You need to divide the remaining 90 degrees in a ratio of 8:1. With ratios, add them together to find the number of parts: … Continue reading Find the number of degrees in each acute angle
Short answer, the traveling time to: the Moon: 3 days Mars: 6 months closest star system (Alpha Centauri): 70,000 years (at Voyager speed) Milky Way crossing: 1.7 billion years Unless we master wormhole, warp factors, or hyperspace travel, it will be the Solar System only. Hey good idea. Let’s go to the nearest stellar system … Continue reading Besides moon or Mars exploration
Considering there’s about a 3 million mile difference between the closest and farthest points of Earth’s orbit from the sun, we wouldn’t notice the slightest difference. Plus, if we were 7000 miles closer now, we’d be 7000 miles farther away in 6 months.We wouldn’t notice, although it could probably be measured with instruments… as it … Continue reading Would happen if the sun moved 7000 miles closer to earth
There is always a cause for an effect. But we can’t always measure that cause; so we are stuck with measuring the effect that is observable. And that’s the crux of the legerdemain we call quantum physics. So we measure what we can of the universe to infer what the cause was based on those … Continue reading The big bang
The most rational assumption is that there is only one timeline. This timeline has an ambient rate of flow of time. This rate of flow of time can be changed yet it is mostly a constant. A person who will travel backwards in time will need first to change the rate of flow of time … Continue reading Grandfather paradox is meaningless
Between -31 and -10 is a difference of +21 In order to have *two* means, we want to divide that into *three* sections: 21/3 = 7 So add 7 to get to the first mean: -31 + 7 = -24 And 7 again to get to the second mean: -24 + 7 = -17 As a double-check, notice … Continue reading Identify two arithmetic
It’s an isosceles triangle so u and v are equal and Pythagoras requires that u² + v² = (8√2)² Since u = v then u² + v² = 2u² = 2v² = 128 2u² = 2v² = 128 u² = v² = 64 u = v = 8 If the answer sheet says u = v = 4, … Continue reading I thought U and V equaled 4 times the square root of 2.
crushed? exactly what does this mean? Guessing you mean the cube is of sheet metal, and it is cut up and formed into small cubes. But the total area has to be the same, which is 6 m² or perhaps the cube is of solid metal (which cannot be crushed) and melted down and formed … Continue reading A cube of 1 m edge length is crushed in order to get small cubes of edge length 1 mm.
To go “back” would necessitate having been there in the first place, which of course no human being ever has, nor will a human being ever go there in the future. There has never been any definitive proof that human beings walked on the moon for the very simple reason that Earth is a self-contained … Continue reading we been back to the moon?
Look for a 50 or hundred inch lense on the private individuals telescope. It’s quite a long ways for a 4 by 6 view of the suface. Oh you don’t see those? Well pshaw pshaw then you ain’t gonna photo nothing but mountains. Of course there are photos NASA shows them to you all the … Continue reading Private individuals have TELESCOPES capable of taking photos of the Moon
